calculates a MultiPolygon of the area covered by a graph

type Error

Required Methods

fn covered_area(
    &self,
    reduce_resolution_by: u8
) -> Result<MultiPolygon<f64>, Self::Error>

calculates a MultiPolygon of the area covered by a graph

As the resulting geometry will be quite complex, it is recommended to reduce the h3 resolution using reduce_resolution_by. A value of 3 will make the calculation based on resolution 7 for a graph of resolution 10. Reducing the resolution leads to a overestimation of the area.

A slight simplification will be applied to the output geometry and eventual holes will be removed.
